Is it the gage or load that matters most? Will a 20ga have less recoil then a 12ga using a 2 3/4 in both? My 12ga days are over with some burcitis/arthritis in my shoulder. Tried limber saver devices etc etc nothing makes it anymore pleasant. Was thinking of going to a .410 as house gun but I want to be able to keep up with practice at the range sometimes.
